It happens that in short notice I will be giving advanced level cocoon
caching course. You might want to consider joining if your boss allows
you to :-) It will cover all kinds of caching starting basic from
caching in browsers, from browser to proxy, from browser/proxy to
application, between applications (Cocoon-Slide), Cocoon pipeline
(event/expires)caching, internal component caching, SourceValidities
like TimeStamp, Expires, NopValidity, EventValidities + JMS, Cocoon
status page + understanding what's in, what caches are available, etc
etc, and a set of tools to help you understand where your caching fails.

It is unrelated to caching, so no. But without it, it does not interrupt
caching either :-)

*Actions* never implement CacheableProcessingComponent!! You can
implement it, but getKey() or getValidity will never be called.
CacheableProcessingComponent only serves for caching of
SitemapModelComponents (like generator, transformers and serializers).
Actions are unique sitemap components merely used to perform processing.
This means, even in cached pipelines, they are called.
What would be to cache about an action anyway? See [1] and [2] for
documentation about Actions and CacheableProcessingComponent contracts

Just to be sure, this LogLevel class does check for something like,
this.getLogger().isDebugEnabled()
this.getLogger().isWarnEnabled()
Etc? Not checking this is quite costly.
